The changes are done in settings/siteaccess/linuxorable/menu.ini.append.php
I really don't known what append. I did a grep -R "MenuContentSettings" * in eZP install folder and the only config files returned are settings/menu.ini, settings/siteaccess/admin/menu.ini.append.php and settings/siteaccess/linuxorable/menu.ini.append.php
I can remove all TopIdentifierList[]=folder in these files, folder objects are always displayed. And I can change all TopIdentifierList[]=folder by TopIdentifierList[]=my_folder, my_folder objects are not displayed and folder objects yes !!!
Maybe, doing an upgrade from 3.7.5 to 3.7.6 will solve the problem.

Even I never changed anything in these files, I checked design/base/template/menu/* files from 3.7.5 and they are the same weight than 3.7.6 files.
You can see here:

PS: I never did it before, but restoring a mysql dump from an old version to a new installation is really easy and works fine. So, you can have a new site take less than 1 hour. Great eZP team job !!
